Working with Generators

Generators in JavaScript provide a way to define an iterative algorithm by writing a function that can maintain its state across multiple calls. They are defined using a special syntax with the function* keyword. Generators allow you to pause and resume the execution of a function, yielding values one at a time.

Creating a Generator:

You define a generator function using the `function*` syntax. We use yield keyword to yield values one at a time.

Example:

function* myGenerator() {
    const x = yield 'Start';
    yield x * 2;
}

const generator = myGenerator();
console.log(generator.next()); // { value: 'Start', done: false }
console.log(generator.next(3)); // { value: 6, done: false }
console.log(generator.next()); // { value: undefined, done: true }

Generators provide a powerful way to work with iterative algorithms, asynchronous operations, and lazy evaluation in JavaScript. They offer a clean and concise syntax for defining iterable sequences.
